I think probably Jinwoo + Guwon is living in their own bubble or Jinwoo probably hasn't grasp the entire situation just yet but the other people at the compound are probably just like Gyeongha, on survival mode.
Jinwoo probably doesn't realise it because he's in Guwon's favour.

Omg I like this theory. Like everyone there sees jinwoo as some wacko who is denying their reality. And guwon is just feeding his delusions. This could also explain why he hates seeing blood and death. Then those moments when he blacks out and is suddenly in survival mode, could be an indication that he knows what world he’s living in, but chooses to dissociate himself from reality.
